The difficulty in evaluating the residual real risk in sites characterized by previous activities of uncontrolled MSW disposal can lead to the application of inappropriate or overdimensioned intervention techniques.

The achieved results form the scientific base of the area recovery plan through actions of in site residual issue control. The main element of the proposed action is the creation of a bio-active coverage made up of a mixture of compost and vegetable ground able to check the gaseous substance and to reset the leaching towards the subsoil.

Abstract
The difficulty in evaluating the residual real risk in sites characterized by previous activities of uncontrolled MSW disposal can lead to the application of inappropriate or overdimensioned intervention techniques. An alternative approach can be used instead: creating systems able to accompany, and possibly accelerate, the phase of complete stabilization with active issue control systems. The present paper shows the results of the study carried out on a landfill used by the Town of Matera (Italy) from 1975 to 1990. The environmental conditions have been restored by means of a characterization plan based on geognostic knowledge, geophysical investigations and on the analysis of the waste contained in the landfill. The achieved results form the scientific base of the area recovery plan through actions of in site residual issue control. The main element of the proposed action is the creation of a bio-active coverage made up of a mixture of compost and vegetable ground able to check the gaseous substance and to reset the leaching towards the subsoil.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
